I have no idea about the 930, but I can tell you that I fitted some replica turbo twists to my 911 that needed spacers and I ended up needing approx 30mm of spacers. This was worked out properly by guys that build race cars from scratch to maintain the correct centre line of the wheels.
I think I bought them from here in the UK. They are actually hub adapters to keep the wheel centred. As Craig says, when you look through the wheel and see them they look *****.
